Siliqua - Arcadius VIRTVS ROMANORVM, Treveri

Trier's mint was among the most productive in the western empire during the late fourth century, supplying silver to an administration stretched thin by usurpation, barbarian pressure, and the practical division of imperial authority between east and west. Arcadius, elevated to co-emperor by his father Theodosius I in 383, appears on these siliquae as a ruler of the western court's making — the coins struck at Trier before his father's death in January 395 formalized what was already a fragmenting command structure.

RIC IX 106b distinguishes this issue by officina and reverse type within a tightly clustered series. The siliqua denomination itself was already shrinking in weight across this period, a gradual debasement that accelerated after Adrianople.
